| Abstract: | The digestive system of 6 teleost fish species with stomach living in freshwater, Channa argus, Siniperca chuatsi, Microperus salmoides, Pelteobagrus fulvidraco, Silurus asotus, Monopterus albus, were observed by using comparative anatomy method. The morphological features of the teeth, pharyngeal teeth, linguae and branchial rakers concerning with feeding were described. The they length, head length, snout length, mouth cleft length, mouth cleft width and oral cavity length were measured. The morphological characteristics of stomach,pyloric caeca, liver and pancrese, and gall bladder were also described through dissection. The oesophagus length, stomach length, stomach diameter, intestine length, digestive tract length and abdominal cavity length were also measured, and concerning ratios were calulated. The relationship between the feeding and the morphological characteristics of digestive system was discussed. |
